1991
Gibbs, I.H (Caribbean Agricultural Research and Development Inst., St Thomas (Barbados))
The sugar cane stalk borer Opogona sacchari Bojer (Lepiodoptera: Hierocestidae) was found damaging "White Lisbon" yam tubers in storage at Hannays Plantation, Christ Church. " Oriental" tubers stored in the same building were unaffected. A description of the pest, its distribution and recorded hosts are given. Laboratory choice and no-choice tests suggested that O.sacchari preferred the "White Libson" tubers affected with dead skin to those of the "White Lisbon" tubers with healthy skin of the "Oriental" tubers. The level of internal damage by the insect larvae also seemed to influence the degree of tuber sprouting and consequent growth of the sprout. Chemical control recommendations are included.
